SHUTTLE-BOX-OPERATING MECHANISM FOR' LOOMS.

SPECIFICATION forming art of Letters Patent No. 744,333, dated November 17, 1903.

Application filed December 10, 1901. Serial No. 85,306. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE Goonnnvn, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Shuttle-Box-Operating Mechanism for Looms; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to mechanical movements, and it has reference particularly to a mechanism of the nature of that required in looms for transmitting power to the shuttleboxes from their prime actuating means.

As adapted particularly for transmitting power to the shuttle-boxes of looms my invention has for its object to render it possible to control a set of boxes corresponding to the extreme number of shuttles which it would be practicable to have in actual operation in the loom andto make the mechanism even convertible, if necessary, from one controlling a given number of boxes to one controlling more or less boxes; to eliminate lost motion and make the movement of the parts perfectly positive and exactly timed, whatever its extent, so that no matter how widely may be spaced the boxes corresponding to any two succeeding calls from the pattern, said boxes will be immediately responsive in assuming a position where their shuttles may be properly discharged onto the batten, and so that while in that position said boxes may stand perfectly stationary, and to make the motion of the parts such that their tendency as, for instance, that of the shuttle-box structure, which is usually heavyto produce vi-- movement; Fig. 2 is a similar view of a in the drawings as disks.

proved form of shuttle-box structure which may be used with my mechanical movement.

a design ates two rotary shafts on which are fixed so as to rotate therewith parts 1), shown On the disks b are pivots c.

To the pivots c are connected rods (Z, which, as shown in the drawings, are suspended from said pivots.' Between the rods (Z is disposed a floating or bodily-movable wheel or pulley 6, having a peripheral groove f. The

groove of this pulley receives straps or bands g h, the latter of which extends over the pulley, while the former extends under it, their ends being secured one to one rod d-and the other to the other rod d, as shown in the drawings. In order to render the throw of one of the rods d variable, the pivot 0 thereof is arranged in a slot iof the corresponding disk b, and in order to adjust the bands g and h one end of the band 71., say, is connected to one of the rods d by means of a threaded hook j, secured to said rod by nuts k. The groove in the pulley also receives each rod and so guides it. a

Z denotes a lever which corresponds to'the box-rod lever of a loom, the same being fulcrumed in that adaptation of my invention shown in Fig. 1 of the drawings on the lower end of a rod m, as at n. This rod is suspended from an eccentric pivot 0 on a disk 19, which is carried by another rotary shaft q.

In the modified form of th e invention shown in Fig. 2 lever Z has its fulcrum centrally of another grooved pulley r, which is disposed between two rods 8 and t, suspended from eccentric pivots u on disks o, secured on rotary shafts w. Disk rand rods 8 and t are operatively connected by straps or bands a: in the same manner that disk e and rods (1 are connected.

At y the means for connecting the box-rod with the lever Z is secured to said lever.

The shafts a a and q (and a a and-w, as in Fig. 2) are adapted to be rotated either separately or together in semirevolutions, Any suitable means may be provided for effecting this.

Referring in describing the operation to the mechanism as shown in Fig. 1 and assuming, first, that the shaft q is stationary shafts a are capable of movingleverZto either three or four positions, according as the adjustable pivot c is or is not the same distance from the center of rotation in the corresponding shaft a that the other or stationary pivot c is from the center of its correspondingshaft a. If pivots c are both the same distance from their shafts a, then pulley Q can be made to assume either of three positions-1". c., (1) its uppermost position, where both pivots c are above the shafts, (2) its lowermost position, where both pivots c are below the shafts a, and (3) its intermediate position, where one pivot c is below its shaft a, while the other pivot c is above its shaft a. If the adjustable pivot c is arranged so that it is farther from the shaft a than the other pivot c is from its shaft a, then the pulley may be made to assume four positionsfirst,the uppermost one, where the two rods are in their extreme elevated positions; second, where the right-hand rod remains up while the left-hand rod is down; third,where the right-hand rod is down while the left-hand. rod remains up, the position which this movement imparts to the pulley being different from the previous one, because since the pivots c of the rods are differently disposed in their respective disk I) the one has a greater throw than the other, and, fourth, where both rods are down. Of course as the pulley is moved so it imparts its movements to the lever Z, which in turn transmits the motion to the shuttle-boxes.

By imparting semirotations to shaft (1 a higher number of positions than four may be assumed by the pulley c. The movements of the pivot 0 about shaft q now cause the fulcrum of the leverZ to assume either of two positions, as illustrated in Fig. 1. For then as the pulley c is moved to any of its four positions by its rod (Z the lever will stand when its fulcrum is at one of its positions at angles which are all different from the corresponding angles which the pulleys impart to the le- Ver when the lever is in its other positions. The result is that the end of the lever which is connected to the shuttle-boxes is capable of assuming eight different points. To carry out this principle of operation still further the mechanism for moving the fulcrum of lever Z has only to be modified into that form thereof shown in Fig. f3,so that'the fulcrum of the lever is capable of assuming more than two positions in the same manner that the parts a, Z), (Z, c, g, and h in Fig. 1 cause the lever to move about its fulcrum to more than two positions.

It should be remarked that during the intervals in which any particular shaft to (or q or w) is idle (and these intervals are variable in order to effect the movement of the shuttle-boxes from any one to any other position) they are preferably secured against movement by spring-controlled stop-levers z, pivoted at l and bearingagainst diametricallyopposed projections 2 on the disks b, (p and Inasmuch as it would be i mpractical to operate too high a number of shuttle-boxesin the ordinary form vertically, because a body so large and ponderous as the shuttle-boxes would then form would cause undue vibration and jar, I prefer to dispose the boxes in circular or cylindrical arrangement. Therefore, referring to Fig. 3, 3 is a shaft which is supported in any suitable manner and which carries a rotary series of cylindrically-arranged shuttle-boxes 4, having a pulley 5, around which and to which is secured the loop 6 of a strap 7, the ends of which extend up and down tangentially from the pulley and are secured to the box-rod 8. This box-rod is the part which is connected through any suitable means at 3 with the lever Z.

The construction and arrangement of the parts of my mechanism are such that I am able from several considerations to effect a great economy of power and to reduce lost motion and vibration in the loom practically to a minimum. Fol-instance, it doesnottakc so much power to operate the lever Z and the boxes through the pulley c as it would if the power were applied directly to the end of the lever, and, moreover, since the power is always acting tangentially of the pulley it constantly acts uniformly thereon. The boxes may be counterbalanced by the weight of the pulley and the rods (Z, which reduces vibration, and lost motion may be practically eliminated by tightening up the bands 9 and h. It will be observed that the bands when taut hold the rods positively in the groove of the pulley. Again, the normal or idle positions of either of the rods (Z being on dead-centers the work which the power has to perform in each turn of the parts which control said rods (Z is not thrown upon it suddenly, but gradually.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
